# NOTE: Mechanism overview is presented in ./README.md.
# Submodule consistent states:
# - NOT initialized (submodule trees are not populated at all);
# - initialized, bound to saved commits;
# - initialized, tracking remote origin (only for FUEL_TRACK_REMOTES);
# - patched (local patches are applied);
# In order to keep things sort of separate, we should only pass up (to main
# Makefile) the fully-patched repos, and gather any fingerprinting info here.
# Fuel@OPNFV relies on upstream git repos (one per component) in 1 of 2 ways:
# - pinned down to tag objects (e.g. "9.0.1")
# - tracking upstream remote HEAD on a stable or master branch
# FIXME(alav): Should we support mixed cases? (e.g. pin down only fuel-main)
# To enable remote tracking, set the following var to any non-empty string.
# Leaving this var empty will bind each git submodule to its saved commit.
